THose chymicall Medecines which remaine, Glasses, Regulus-chaulks, and certain Powders, we will annex in this Chapter.
First, Glasse is prepared from the chaulks of things; * 1.1 and vi∣trification, for the most part, is the last resolution of things: for Ashes, or Chaulk is to be poured into a very strong fire, and sometimes Borax is added to ripen the fusion, or other fusill Powders, but fufill matter is poured into a Basin made hot, or upon some table.
Glasse of Antimony is predared in this manner; * 1.2 also Am∣ber of Antimony, or as others would have it, of Mercury. Purging cups may be made of these Glasses, also Rings, Mo∣ney: If glasse of Jupiter, or glasses, or Amber of Antimony, * 1.3 if they are set into the bottome of a cup, or into a Ring, or any Coyne: Of Glasse of Antimony golden; see the institu∣tions, as also of Regulus of Antimony.
Moreover, the next to these are chymicall Powders and Chaulks; as for them, the first that is referred to them, is called Antimony fixt, or Diaphoretick, which is made if An∣timony be burnt so often with Nitre, till it become white and fixt. Milk of Venus, how tis prepared, the Institutions shew.
To these belong Dreggs, or Faeculae, * 1.4 as they are called by later Chymists, which are certaine Farinaceus Powders prepared of the juice of certaine roots beaten, or expressed or extracted by some liquor, namely, if a juice, or liquor be put into a cold place, the Faeces of their owne accord settle in the bottome, which when the moisture is poured off, are dryed and kept; the chiefest that are in use are the F••ces of Briony, Wake Robin, Piony, and Orrice, as also of Dra∣gon.
